reflective eyes

In animals like cats, the reflections at night are because of an extra membrane, the tapetum lucidum, behind the retina, which reflects light back to the retina, so at night each bit of light gets two chances to hit the retina. People don't have one. btw, i'm in second year high school bio

reflective eyes

I decided not to put it in the article because I wanted to concentrate on humans only. If i did animals I'd have to include flies eyes and lots of info that I don't know much about. I only really do humans.

Wish I was back doing 2nd year biology, doing 2nd year optometry and it's getting complicated.
